Local copying and local discrimination as a study for nonlocality of a set of states
Masaki Owari, Masahito Hayashi · Physical Review A · 2006
We focus on the nonlocality concerning local copying and local discrimination, especially for a set of orthogonal maximally entangled states in any prime dimensional system, as a study of nonlocality of a set of states. As a result, for such a set, we completely characterize deterministic local copiability and show that local copying is more difficult than local discrimination.
